IMPRGJEFdENT IN LAMP-WIQK TUBES.

Specification forming part of Letters Patent No. 115,607, dated June 6,1871.

1' 0 all whom it may concern:

, Be it known that I, EDGAR K. HAYNES, of Boston, in the county ofSufl'olk, State of h'iassachusetts, have invented a new and usefulLamp-Wick Tube; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon, in which- Figure1 is a perspective view embodying my invention. Fig. Zis a verticallongitudinal section of the same. Fig. 3 is a top view of the wick-tubeand braces. Fig. 4 is a detached vertical section of the Wick-tube.

The nature and object of my invention are to prevent the heat frompassing down the wick-tube.

In all coal-oil burners that are used without a chimney there is anoffensive odor produced, which injures very much the sale and use ofthis class of burners. I have found by experiment that the greater partof this odor is caused by the heat passing down the Wicktube insufficient quantity to produce gas or vapor from the oil at the lowerend of the wick tube, which passes out of the tube through the aperturein which the toothed wheel works to raise and lower the Wick. It is alsoformed from any oil that may be on the base of the burner.

'lo obviate this difficulty of.the heat passing down the wick-tube Iconstruct my tube in sections, one of which is made of metalsufiiciently thin to cool by the action of the air outside and the oilinside, thereby preventing a sufficient quantity of heat from passingdown the tube to form gas or vapor.

A is a section of very thin metal, not as thick as commonWriting-paper.It is soldered,

locked, or otherwise fastened to the top of the lower section D 5 .or itmay be a continuation of D drawn out thin to save making the joint. Thesection D is of the usual form and thickness. To give strength enoughfor the toothed Wheel F to work against it should be as short aspossible, leaving only a sufficient space above the cap E to make theproper connection. I have now a Wicktube; but the section A is notsufiiciently strong for practical use. To strengthen and support it Iconstruct a ring, B, in the form or" the top of the tube, slip it overthe outside, then turn or look the top end of the tube A over the ring.This protects and strengthens the top. To brace and support it I connecta sufficient number of arms or braces, O 0, to the ring B, and fastenthe other end to the base of the burner, to the cone or deflector, orany permanent place, according to the construction of the burner; or thethin section A may be corrugated enough to give it sufficient strengthWithout the use of the ring B and braces (J C.

IIith a tube constructed in this manner, and a burner with a base largein diameter, to con nect the deflector to, to prevent too much heat fromthat direction getting to the base of the wick-tube, we have a burneralmost entirely free from smell.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

' The wick-tube A D, when the upper part A is made of thin metal,substantially as and for the purpose herein described.
